The Season of the Rodent

Rats and mice are very active this time of year.

Autumn can be one of the nicest times of the year. The leaves change color. The temperature is perfect. Even the sky just looks bluer. Everyone knows Winter is Coming, but at least fall makes for a nice consolation. At least, it should. Unfortunately, “everyone” knows Winter is Coming. Everyone includes rodents.

When the temperature drops, rodents start trying to get into your place like their lives depend on it. Nothing ruins the last nice weeks we have left like a rat infestation. You should be enjoying the all-too-fleeting pleasures of autumn while you can–not stressing out about the rats in your basement. Here are four good ways you can ensure unwelcome guests stay out of your home this fall.

Seal Doors and Windows

Rodents can feel this warm air escaping from outside, and they can follow it back to its source. Mice and rats are notorious for their ability to squeeze through tiny gaps. Even a tiny crack in a window frame’s weather-sealing is more than enough space for a motivated rodent.  

Double-check every window in your home. Make sure the window pane sits properly and the weather-proofing hasn’t worn down or peeled away. Look for cracks or other damage in the frame itself, as well. Check for condensation on the window sill and run your hand along the frame to feel for cool air. If you find either, it means there’s probably a draft around the window. Find and seal up this draft, and you’ll go a long way toward keeping rodents out of your home. Once you’re finished with the windows, follow these same steps at each outside door.

Put Screens over Vents

put screens over your vents this fall to keep rodents outYour home transfers outdoor air in and out from more places than you’d think. Pretty much every water-using appliance needs to have a ventilation system to function properly and prevent excess humidity. Vents work by transferring hot air out of your home. Unfortunately, rodents can feel this hot air from outside just like they can feel drafts. If your vent systems aren’t appropriately covered, then rats can use them to crawl into your home.

Remember: you need to leave enough space in your vent system to let air pass through. If you don’t, you’re defeating the purpose of having ventilation in the first place. Putting screens over your vent’s outlets will allow air to flow normally while keeping rodents out. Remember, however: rats and mice are notorious gnawers. Check on your screens annually to make sure the annoying munchers haven’t chewed their way through. If any of your screens have been noticeably damaged, you should replace them as soon as possible.

Check Outside

Look for cracks where you can see light from inside, or where you can feel heat escaping. Pay special attention to areas of the home where utilities like water and gas enter the building. These access points tend to have gaps juuust wide enough for rodents to enter.   

After you’ve “secured the perimeter,” you could take this opportunity to de-clutter your lawn. Fall tends to drop all kinds of debris into your yard. Rodents use fallen leaves, overgrown bushes, weeds, and other clutter as a means to get close. Keep clutter like leaf piles or firewood at least five inches away from your home. Keep trimming your bushes and lawn until they stop growing for the season. Make sure tree branches don’t brush up against your home. This all might sound extreme, but rodents really will use anything they can.

Clear the Clutter

clean up your basement this fall to keep rodents outYou didn’t think you’d get away with only cleaning the outdoors, did you? Sorry, but once you’re finished de-cluttering your yard, it’s time to move inside. Messy basements and attics attract rodents looking for warm, dark, and hidden places. The more space they have to move around in secret, the more attractive your home will look to them. One of the best ways to make sure rats leave you alone is just to demonstrate that you know they’re there.

First, pick up boxes and bags lying on the floor in your basement. Sort through them, organize them, and keep them on shelves or in cupboards. Keep your floor as clutter-free as possible to make rodents feel uncomfortable crossing it. Vacuum and dust every room in your home at least once every two to three weeks. You should vacuum any rooms where you eat or prepare food even more frequently. If you can deprive rodents access to the resources they came looking for, they’ll start looking elsewhere for them.

 

The stakes never get higher than they are right now. Rodents that get into your home during warmer months come and go as they please. If rodents get into your home in fall, however, they’re staying for the duration. Winter is hard enough without sharing your space with furry roommates.

The Rats of Detroit and How to Stop Them

A recently conducted study found that Detroit is the Ninth most rat infested city in the US. Detroit’s rat population is on the rise.

Why are rat populations in Detroit becoming such a problem? Is there anything we can do to keep the population down, or least keep the rats out of our homes? Griffin wants to answer these questions, so you know where your rats might be coming from and what you can do about it.

Why Do Rats Love Detroit?

Like most pests, rats have simple needs and want to fulfill those needs as easily as possible. They flock to the parts of the world where the things they need are abundant, easily found, and as risk-free to pursue as possible. Cities like Detroit meet these criteria exceptionally well. Here’s what rats need, and how Detroit gives it to them:

Food

Most rats rarely wander further than their “home range” of 50 to 150 feet in any direction from the nest. Rats have poor eyesight, and prefer to know the environments they live in well to limit risk of predation or starvation.

A rat’s environment has to ensure that they can get enough food to survive while staying close to home. Cities solve this problem. High population densities create a lot of trash, which rats can use to feed themselves without ever leaving the nest. The next time you see a rat, check to see if there’s a dumpster nearby. Chances are, their nest isn’t far off.

Water

Just like pretty much everything else, rats need water to survive. Rats have to find a way to get a sustainable source of water close to their homes. It also has to be safe and relatively consistent, since rats are vulnerable while they drink. Cities solve this problem too.

Not only is there always a surplus of free water for rats somewhere, that water is often safe to linger around. Adult brown rats require only an ounce of water daily. Leaking pipes, broken valves, or condensation are more than enough to sustain them. Cities provide more chances to find water sources that can be accessed safely than any other environment would.

Shelter

The other thing all rats need to survive is warmth. When Winter comes, rat’s fur isn’t enough to protect them from freezing. They have to seek shelter in warm enclosures.

Cities provide for this need better than anywhere else, too. Old buildings, buildings that have fallen into disrepair, abandoned buildings, and unstaffed warehouses are all perfect places for rats to wait out the winter. They have all they can eat while they wait! The nooks and crannies of cities provide more safe shelter than anywhere else, and rats take advantage.

Keeping Them Out

Know that you know why rats are coming into your city, you can apply that knowledge to keeping them out. Rats go to places where they can easily get what they need. If you want to keep them away, you have to make sure they can’t.

Food

The most important way you can avoid attracting rats is by depriving them of food sources. Use tightly sealed, thick garbage bags to store and transport all your trash. Rinse out empty food containers before disposing of them. Keep your home’s garbage in a sealed container and keep it off the ground. Take your garbage out frequently, and make sure the dumpster you’re taking it out to is 15 feet or more away from your home.

Clean up your kitchen and dining surface immediately following each meal. Vacuum the rooms you eat in frequently and thoroughly. Make sure you put away groceries in their proper places. Don’t leave food out on the kitchen counter, especially not fruits or breads. Don’t leave snacks out after you’re finished with them, and don’t leave dishes in the kitchen sink.

Water

Once you’ve dealt with the food sources, look for places where rats could be getting water. Make sure you don’t have any leaking faucets, shower heads, or pipes. Invest in a humidifier for humid areas of your home. Look for drafts that could be letting air in. Make sure other water-based appliances like your dishwasher and refrigerator aren’t leaking either.

Finally, look for moisture. Make sure you’re always running your bathroom fan when bathing. Dry and put away dishes as soon as the dishwasher’s done with them. Rinse out bottles and cans before recycling them, even if almost all the liquid in the container is gone. Seal recyclables in bags and take it out frequently.

Shelter

Keeping food and water away will help, but if you really want to keep rats out, you have to make sure they have no way of getting in. Rats can squeeze through openings no larger than the size of a nickel, so don’t assume any cracks or gaps are rat-proof. Seal cracks in your foundation or walls with caulk. Replace worn weatherstripping, screens, and wooden frames. Make sure your windows and doors are properly sized and seated.

One of the most common places rats sneak in is around utility lines entering the building. Inspect that area and seal any gap you find between the lines and the house. Rats can also scurry up surprisingly steep surfaces such as trees to get on top of a house, so make sure your landscaping doesn’t create any likely paths to your roof. While you’re at it, try putting screens over your chimney and plumbing vent.
